Build real-world, industry-strength data storage solutions with time-tested design methodologies using CassandraAbout This BookExplore design patterns which co-exist with legacy data stores, migration from RDBMS, and caching technologies with CassandraLearn about design patterns and use Cassandra to provide consistency, availability, and partition tolerance guarantees for applicationsHandle temporal data for analytical purposes Who This Book Is For This book is intended for big data developers who are familiar with the basics of Cassandra and wish to understand and utilize Cassandra design patterns to develop real-world big data solutions. Prior knowledge of RDBMS solutions is assumed.What You Will LearnEnable Cassandra to co-exist with RDBMS and other legacy data storesExplore various design patterns to build effective and robust storage solutionsMigrate from RDBMS-based data stores and caching solutions to CassandraUnderstand the behaviour of Cassandra when trying to balance the needs of consistency, availability, and partition toleranceDeal with time stamps related to data effectivelySee how Cassandra can be used in analytical use casesApply the design patterns covered in this book in real-world use cases In Detail There are many NoSQL data stores used by big data applications. Cassandra is one of the most widely used NoSQL data stores that is frequently used by a huge number of heavy duty Internet-scale applications. Unlike the RDBMS world, the NoSQL landscape is very diverse and there is no one way to model data stores. This mandates the need to have good solutions to commonly seen data store design problems. Cassandra addresses such common problems simply. If you are new to Cassandra but well-versed in RDBMS modeling and design, then it is natural to model data in the same way in Cassandra, resulting in poorly performing applications and losing the real purpose of Cassandra. If you want to learn to make the most of Cassandra, this book is for you. This book starts with strategies to integrate Cassandra with other legacy data stores and progresses to the ways in which a migration from RDBMS to Cassandra can be accomplished. The journey continues with ideas to migrate data from cache solutions to Cassandra. With this, the stage is set and the book moves on to some of the most commonly seen problems in applications when dealing with consistency, availability, and partition tolerance guarantees. Cassandra is exceptionally good at dealing with temporal data and patterns such as the time-series pattern and log pattern, which are covered next. Many NoSQL data stores fail miserably when a huge amount of data is read for analytical purposes, but Cassandra is different in this regard. Keeping analytical needs in mind, you’ll walk through different and interesting design patterns. No theoretical discussions are complete without a good set of use cases to which the knowledge gained can be applied, so the book concludes with a set of use cases you can apply the patterns you’ve learned.Style and approach This book is written in very simple language and an engaging style complete with examples in every chapter and real-world use cases at the end of the book.

Earth is our Business takes forward the argument of Polly Higgins’ first book, Eradicating Ecocide. This book proposes new Earth law, but it is also about something more than law: it advocates a new form of leadership which places the health and well-being of people and planet first. Polly Higgins shows how law can provide the tools and be a bridge to a new way of doing business. She argues, in fact, that Earth is the business of us all, not the exclusive preserve of the executives of the world’s top corporations. Expanding on the proposal in her first book to make Ecocide an international crime, this book sets out the institutional framework for sustainable development and international environmental governance. It proposes new rules of the game to transform our economies, energy supplies and political landscape in a radical, but practical, way. The implications of Polly Higgins’ proposal are far-reaching and profound. Like her award-winning first book, Earth is our Business is written for anyone who is engaging in the new and emerging discourse about the future of our planet and sustainable development. Instead of merely examining the problem, Earth is our Business sets out a solution: new rules of the game. They are, says Polly Higgins, a new set of laws based on the sacredness of all life. Included as appendices are a draft Ecocide Act, a proposal for revising World Bank investment rules, and the indictment used in the mock Ecocide Trial held in the UK Supreme Court in September 2011.

The Teaching of Reality is, as far as we know, the first translation into English of Tattvopade?a, a work attributed to the great spiritual teacher ?ankara.

The reader is led through a systematic process enabling the real Self to be realised in practice.

The stunning, specially commissioned cover illustrations are one of the great joys of the New Naturalist series, lending it a distinctive style which has inspired nature enthusiasts for many decades. The Collins New Naturalist series is the longest-running and arguably the most influential natural history series in the world with over 100 volumes published in over 60 years. Throughout the years, the highly characteristic dust jacket illustrations have become iconic, lifting the books to a level of collectibility and increasing the level of admiration for an already well-established and respected series. With early cover illustrations prepared by Clifford and Rosemary Ellis, later and more recent covers have been designed by Robert Gillmor. Featuring prints of the awe-inspiring artwork of the New Naturalists, the book will offer a unique insight into Gillmor’s approach to each subject matter and the intricate and creative way through which he has brought his own distinctive style and craft of printmaking to the New Naturalist series. Marren explores the findings from the Ellis archive, which has thrown up considerable information on how the old covers were developed, approved, in some cases rejected, and then proofed. The Art of the New Naturalists offers a fascinating insight into how the creation of these eminent cover designs has developed and progressed and will be essential reading for everyone interested in the frantic workings behind the seemingly serene collection of artwork that is one of Britain’s iconic book series.

Adonais begins as he stands on the Iberian Peninsula and looks out towards the coast of North Africa, fighting for the strength to go with his inner leadings and follow his destiny that lies beyond that coast. The story observes the young Friar as he makes his journey from the Peninsula?s southern tip through the Alpujarra to a Gharnata that is feeling a new rise in sectarian tension and is hearing news of violent events across the border in Christian Sevilla. In Gharnata he meets his childhood friend Miriam in the house of Rabbi Andrew, the spiritual head of Gharnata?s distinguished Jewish population. They agree to share the journey together to her forest community that is on the way to his final destination which is the Christian frontier city of Jaen.

The Gamification design process starts by profiling players and creating levels of achievement towards meeting learning outcomes. Each task is defined, valued, and sequenced. Motivation loops are devised to keep the momentum going. In a gaming studio, this approach would require a team of specialists with a large budget and time frames. Preparing for a class rarely has these optimal conditions. The approach used in this book is to introduce game elements into the course design gradually. First, apply gamification to just one lesson and then build up to gamifying a series of lessons over a term. Each example will indicate the difficulty level and time investment. Try it out to see what is most effective with your learners and choose wisely in your use of technology. By the end of this book, you will be able to create Moodle courses that incorporate choice, communication, challenge, and creativity.Style and approach An easy-to-follow guide full of screenshots and step-by-step instructions with estimated time frames required to accomplish numerous tasks.
